Application tiled April 15 189 5.

To all whom it may concern,.-

Be it known that I, THEOD ORE HOELZER, of Toledo, county of Lucas, andState of Ohio, have invented certain new and useful Improvements inBall-Mills for Mixing or Grinding; and I do hereby declare that thefollowing is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to the figures of reference marked thereon, which form part of thisspecification.

My invention relates to a ball-mill for mixing or grinding, and has forits object to provide a mill in which different substances may be mixedor ground in one operation in separate receptacles, the receptaclesbeing so arranged that the power necessary to revolve the same isreduced to a minimum.

The invention consists in a revoluble cylinder having a plurality ofreceptacles removably secured at or near the periphery of the same, saidreceptacles being of non-corrosive material having a screw-cap upon oneend, whereby the material to be mixed can be conveniently inserted orremoved.

The invention further consists in the parts as shown, described, andclaimed.

In the drawings, Figure l is a side elevation of a mixing or grindingmill constructed in accordance with my invention. Fig. 2 is a verticalsectional View of the same. Fig. 3 is a detail view of one of thereceptacles removed from the mill.

l designates a frame in which is secured the shaft 2. Upon the shaft isxedly secured a cylinder 3, said cylinder having a plurality of openings4 at or near the periphery thereof, the openings being of a size toreceive receptacles 5. Receptacles 5 are preferably formed of glass,porcelain, or analogous non-corrosive Serial No. 545,834. (No model.)

substance and are provided with a removable cover 6, screwed upon thesame at one end, whereby the contents can be removed or inserted.Secured upon the shaft 2 are pulleys '7, by which means the shaft andcylinder are revolved.

In operation the material to be ground or mixed is inserted in thereceptacles by first removing the cover 6, when the cover is screwedupon the receptacle and the receptacle placed in the cylinder, when byrevolving the cylinder the material is caused to be agitated andthoroughly mixed or ground, it being understood that in the grindingprocess there are employed balls, formed of porcelain or analogoussubstance, which, by rubbing against the material as it is agitated bythe elevation of the cylinder, grind the material.

It will be seen that as many different materials may be ground or mixedat the same time as there are receptacles 6, and that by the receptaclesplaced as described in the cylinder the weight is distributed and thepower necessary to revolve the same reduced to a minimum.

What I claim is- In a mill for grinding or mixing, a shaft and means forrevolving the same, a cylinder fixedly secured upon the shaft, a seriesof openings in the cylinder adjacent to, and equidistant from, theperiphery thereof, and receptacles to receive the material to be groundor mixed, secured in the openings of the cylinder.

In testimony that I claim the foregoing as my own I hereby affix mysignature in presence of two witnesses. v
